Yeah the LOTR Minimates have C3 feet. The 2.5" Minimates (these Archers, Aragorn, Orcs etc) have 2 holes on each foot whilst the 2" Minimates (Hobbits, Gimli etc) have the same size feet as the DC Minimates, with one hole.
In fact, due to when they came out, the LOTR Minimates were the first to get C3 feet as they beat the DC C3 stuff to retail.
Oh, and great pics prozac! Really looking forward to this set.
edit - now with feet/stand pics
See Gandalf and Frodo in this pic here with the holes in the feet:
See the clear stand that comes with the 2.5 Minimates:
And finally see how it attaches to the different sized feet:
Obviously they also work with any C3 feet, as this pic shows:
